The domain is the possible values of x.
There are no real values for ln 0 or ln of a negative number so the value of (1 - x) must be > 0
1 - x > 0
-x > -1
x < 1
Domain is x < 1 or in interval notation it is ( -∞, 1)
A 200-degree angle is between 180 and 270 degrees, so the terminal side is in QIII.
Do the operation indicated for that quadrant. Subtract 180 degrees from the angle, which is 200 degrees.
You find that 200 – 180 = 20, so the reference angle is 20 degrees.
hope this helped!

Rectangle: a = w x l
Square: a = a^2
Triangle: a= b x h divided by 2
Parallelogram: a = HH
